While writting vgic v3 init sequence KVM selftests I noticed some
relatively minor issues. This was also the opportunity to try to
fix the issue laterly reported by Zenghui, related to the RDIST_TYPER
last bit emulation. The final patch is a first batch of VGIC init
sequence selftests. Of course they can be augmented with a lot more
register access tests, but let's try to move forward incrementally ...
Best Regards
Eric

History:
- Took into account all comments from Marc and Alexandru's except
the has_run_once still after the map_resources (this would oblige
me to revisit in depth the selftests)
